Fig. 2 is a front elevation of frame, the picker stems and adjustment bar the harvester, portions of the framing broken being omitted, the picker frame moving devices being .shown in a withdrawn position; Fig. 16, a vertical section of one side of the frame, showing the picker carriage, said section being taken approximately on the line y, y, Fig. 1.

Like numerals of reference refer to like parts throughout the several views.

I shall first describe the main frame of the machine, which frame supports the movable picker frame and motive connections with the propelling wheels.

Two rectangular frames 1 and 2 form the main members of the frame and are disposed at the front and rear thereof respectively. The lower central section of both members is left open so as to permit the cotton bush to pass centrally through the frame. These members may be either welded at their angles, or bolted together, and are preferably made of angle iron. Braces 3, 4 of angle iron unite the front and rear members 1, 2 at the top, and like braces 5 (but one of which is shown in the drawings, to wit: Fig. 3) secure the lower portions of the members 1 and 2. A central brace 6 secures the front and rear members 1 and 2 in the center thereof on each side (but one of which is shown). An arch bar 7 extends entirely about the frame, the downwardly extending portions of which are secured respectively with the cross-braces 3, 4, 5, 6, the upper or arched portions of which extends some distance above the top of the frame proper. This barserves as a brace for the entire frame besides forminga means of support for the propelling wheels and attached devices. A bar 8 extends between the mainsection 2 and center brace 7 and is secured thereto, in which is formed bearings for power conveying devices. The frame thus constructed is very light and strong and of convenient shape. y

The propelling wheels 9 upon which the main frame rests, are secured in suitable bearings in the center brace 7 by the axle 10. From the sprocket wheel 11, secured to the wheel 10, a sprocket chain 12 is led to and over a reducing sprocket wheel 13 ,secured upon a shaft 14, having bearings in the bar 8. A larger sprocket wheel 15 is secured upon the shaft 14 and to it rotary motion is given by the sprocket wheel 13. A sprocket chain 16 leads from the sprocket wheel 15 around a smaller sprocket wheel 17 suitably secured in bearings 18, fixed to the frame. A feathered shaft 19 having a feather 2O is rotatably secured within the hanger 21, said shaft having la miter wheel 22 on its end. The shaft 19 moves with the hanger 21 and the sprocket wheel 17 is interiorly slotted to permit the feather 2O of the shaft 19 to work within itin the usual manner, the sprocket wheel 17 having the collar 23, Fig. 11, and a sleeve 23X integral with said collar enters the bearings 18 and transmitting devices for the harvester. Motion is given to the picker stems by means of the miter wheel 22 of the shaft 19,which is connected to the power wheel 9 by sprocket wheels and chains. As this mechanism is duplicated on both sides of the machine, a description of that on one side is sufficient.

The movable picker stem frame is constructed as follows: lt comprises the top front cross-heads 24 and the top rear cross heads 25, the bottom front cross head 26, and the bottom rear cross head which is directly below the top rear cross head 25,said last cross head not being shown,but which will be known as 26 also. The cross head 24 has the bracket 21 cast integral with it, and has downwardly extending bosses 27, as have all the other cross heads. The cross heads have bearings 28 for the transverse extending shafts 29, 30, the shafts 29 extending across and uniting the front and rear top cross heads, and the shafts 30 likewise extending across and uniting the frontandrear bottom cross heads. The outer ends of the transverse shafts are provided with rollers 31, 32 at the front side, top and bottom respectively, and with rear rollers 32n at the top and bottom respectively. Secured within the bosses 27 are upright rods 33, 34, the rods 33 being secured to the rear front heads, and the rods 34 to the rear cross heads.

rlhe rear part of themovable vpicker frame is constructed substantially the same as the front portion thereof, and it is not necessary to illustrate the details.

The cross heads 24, 26 have inwardly extending arms 35 in which the upright shaft 36 is rotatably secured. This shaft carries a miter wheel 37 in gear with the miter wheel 2 on the shaft 19. The bar 38 is secured to the downwardly extending portions of the members 1 and 2 of the main frame, so as to form guides for the upper rollers 31, 32, whileA the lower inwardly extending portion 39 of the members 1 and 2 forms the guide for the lower rollers 32, the upper set of rollers working within the longitudinal section of the main members and the bar 38 and the rollers 32 resting simply on the guide 39. By this arrangement the picker frame can be moved toward or from the center of the machine, or toward the cotton bush carrying with it the shaft 19, so that while said shaft is being rotated and rotation imparted to the upright shaft 36, the picker frame can be moved back and forth without interfering with such rotation. The picker stems 40 are supported at their rear, through the intervention of levers hereinafter described, by the inner upright bar 34a. The front end of the picker stems are supported on the shaft 36 through the instrumentality of devices carried by the upright bar 33a, all of which will be hereinafter described.

Each picker stem being constructed identical, a description ofV one will suffice. It comprises an outer cylindrical shell 41 with perforations 42 adapted to rotate within what I IOO IIO

shall vcall outer and inner cylinder heads. The outer cylinder head 43 is recessed, as shown in section in Fig. 6,and has outwardly extending arms 44,45 provided with holes 46. The head 43 has an outwardly extending yoke 47, provided with a centrally located collar 48, through which the shaft 36 passes and about which the collar is free to rotate. The rear head 49 has arms 50, 5l similar to the arms 44 on the front head 43, and has an outwardly extendinglug 52 with an eye 53 formed thereon. Rods 54, 55 are secured to the arms on the front and rear cylinder' heads respectively by nuts 56, both rods securing the cylinder 4l within the cylinder heads, the rod 5,4 being placed over the top of the cylinder for the purpose of preventing pods, leaves or twigs from being carried around bythe hacklepins, and the rod 55 being placed at one side of the cylinder, and upon which the deiiector and guard are secured as hereinafter set forth. The cam-way 57 is formed on the inner face of both of the heads by securing thereto the outer cam-ring 58 and the inner cam-ring 59, both rings being secured to the heads by the screws 60, the inner cam-ring having an aperture 61. Instead of using screws 60 for securing the cam-rings to the heads, said rings may be secured in the heads by means of screws disposed as at 60a, Fig. 8. A short spindle 62 passes through an aperture in the end of the head 43, having on its outer end a miter wheel 63, which meshes with the miter Wheel 64 on the shaft 36. The miter wheel 64 has a sleeve 65 through which the shaft 36 passes and a set screw 66 for securing the sleeve and miter wheel to the shaft 36.' On the inner end of the spindle 62 is a disk 67, preferably formed integral with the spindle 62. This disk extends at right angles to the spindle 62, and is provided with a series of radially extending slots 68. This disk I shall hereinafter call the slotted head, and one is placed within each cylinder-head. Within the radial slots 68 in the slotted heads at both ends of the cylinder, are placed hackle-bars 69 preferably rectangular in cross-section, and which are provided with radially extending hackle-pins 70, so located that they may be projected out and withdrawn through the apertures or perforations 42 in the cylinder 4l. By the rotation of the miter wheel 63, the slotted head is rotated and with it the hackle bars 69, like motion being communicated to the slotted head at the other end of the cylinder. During this rotation the ends of the hackle bars work within the cam-way 57, located at both ends of the cylinder and project and withdraw the hackle-pins.

By reference to Fig. 9, it will be seen that the hackle-pins are entirely projected on one side, and Withdrawn within the periphery of the cylinder 4l on the other side, and at all times during the rotation of the hackle-pins, one portion thereof is in contact with the cylinder 4l, so that as the hackle-pins rotate, the cylinder 41 rotates with them, the said cyl- Aeld of rotation of the hackle pins.

inder acting as a cleaner to stripthe cotton from the hackle-pins.

By reference to Fig. 7, it will be seen that the cam-plates 58, 59 are adjustable, as the cam-way 57 is formed by the cam-plates which are detachable from the heads 43, 49, and by means of such detachability their relative positions within the heads can be changed, so that the hackle-pins cany be projected or withdrawn at any point about the cylinder if desired, but I prefer their position illustrated in Fig. 9, wherein the withdrawal of the pin commences as they approach the rod 54, and their projection commences as they pass outwardly from the perpendicular axis of the cylinder below the rod 54, so that the pins will be drawn from contact with the cotton during their inward rotation, and also that the bar 54 will co-operate with such' withdrawal to preventA pods, leaves, twigs, dac., from passing beyond it, should they be picked up by the hackle-pins.`

The deflector 7l is secured at one end to the bar 55, the other end resting onthe periphery ofthe cylinder 6l. used for the purpose of lifting the cotton from the cylinder and passing it out from the The detlector 7l may be loosely secured to the rod 55, so as to be thrown out of action if desired. This deflector may be made integral with a guard 72, Fig. 14, and the deflector 7l and guard 72 secu-red to the rod 55 by the screw.73. The function of the guard 72 is to close the opening between the cylinder 4l and the bar L52, when two pickerfstems are superposed, so as to prevent foreign bodies passing through.

The upright rod 33n which is secured to the cross-heads 24 carries jaws 74, having outwardly extending fingers 75. These jaws are provided with a set screw y76 by means of which said jaw is rigidly secured to the rodl 33a. These jaws support the front end of the picker stem by reason of the collar 48 on the yoke 47 passing within the fingers 75 thereof,

This deliector is' IIO and take the weightof each pickervstern from Y 0E the shaft 36 and itsgearing,.and bring such strain upon the rod 33L which is fixed,

and as the miter wheel 65 is adjustable on the shaft 36, and the jaw 74 adjustable on the rod 33a, the front end of the picker therefore can be raised up and down in order to bring the picker stem into a position to enableit to pick cotton at various points on the bush, or

As before stated the rearend of the picker stem is provided with an outwardly extending lug 52, having an eye 53 formed thereon. Extending from the eye 53 .is a lever 77 united to the eye by the pin 78, the outer end of saidl lever being provided with a hole 79. Upon the rod 34a is secured a collar 8O by means of the set screw 81. A lever 82 ending in the collar 83 which passes around the rod 34, is pivotally secured to the lever 77 by the pin 84. Between the set screw 81 on the collar 80, and the hole 79 in the end of the lever 77 extends a spiral spring 85, which normally tends to press the rear end of the picker stem to its position of utmost extension, but which should be so regulated that it will permit the picker stem to give, when such stem meets with any abnormal obstacle, as for instance, a cotton bush thicker or wider than that for which the machine is set to operate upon, in which case if the same was not capable of giving, it would tear and injure the plant. This is only one instance of where the bush itself or the cotton bolls, dac., act to press in the picker stem, when either of them form an abnormal obstruction. This arrangement besides making the stem flexible, enables it to be independently operated, either to he brought toward the field of operation 01 retired therefrom, for supposing the operator desires to throw any one of the stems out of action, he has only to take hold of the lever 77 and move the end thereof outwardly, which will give the picker stem the inward movement, indicated'by the arrow, crossing it in Fig. 4, the lever 77 taking the movement indicated by the arrow, crossing it, same figure, and the lever 82 taking the movement indicated by the arrow, crossing it, and when the act of withdrawal of the stem 85 has been accomplished to any desired degree, the spring 85 will draw the levers and pickers back into the positions they previously occupied. Or should any one of the picker stems be out of action by reason of its being too far from the center having regard to the width of that part of the cotton bush, it can be brought into the field of operation by the contrary movement of the lever 77.

The collar 80 can be set on the shaft 34 by means of the set screw 81 in any desired position, the collar 83 on the lever 82 resting on the collar 80, and being -movable about the rod 34a, so by this means the rear end of the picker stem may be adjusted up and down in the same manner as the front end, as before described.

The means for moving the picker frame will now be described. Upright standards 86 are secured upon the upper portion of the main frame section 2, and like standards 87 are supported in a like manner on the upper portion of the main frame section 1, the standards on both sides of the machine being arranged diametrically opposite each other. Within the standards 86, 87 are rotatably secured longitudinal shafts 88 to which the operating handles 89 are fixed. The shaft 88 permits both ends of the picker frame to be moved synchronously, and preserves the parallelism of both ends of the frame. The front end of the shaft 88 is provided with a downwardly extending crank arm 90 fixed to the shaft,'and the rear end of said shaft is in a like manner provided with downwardly extending crank arms 91. A pitman 92 is pivotally secured to the crank arm 91 at 93, and a like pitman 94 is secured in a like manner to a crank arm 90 at 95. The guide rollers upon which the picker frame is movable are connected with a toggle joint mechanism operated by the lever 89, which toggle joint mechanism is connected and constructed as follows: The outer wheel 3l of the upper front series has a lever 96 secured upon the shaft 29, which passes through said wheel, and the outer wheel 32 of the lower set is likewise provided with a like lever 96. Another series of levers 97 are secured at one end upon'the frame section lat 98. To the pitman 94 is pivotally secured at 99, an upright connecting rod 100, said rod being pivotally connected to the levers 96, 97 at 101, the picker frame being free to move on the tracks and within the guide provided for it, as before set forth, and the toggle joint being connected therewith, the operation of the same will move the picker frame back and forth, and project and withdraw the picker stems.

In Figs. 1 and 2 the frame has been moved out by the toggle joint mechanism to its utmost degree of projection, and in Fig. 15, it is shown as completely withdrawn.

The hackle-pins on the hackle-bars are preferably blunted at the ends, so as not'to tear the leaves of the bush or become fastened in the pods, 'but being left sharp enough to engage the ripe cotton.

Many changes and modifications maybe made in the present structure without departing from thespirit of my invention.
